Question

find the value of p（x）=x²-5x+4 at x= -1​

Answer 1

Answer:

Value of x at x = -1 is 10

Step-by-step explanation:

Procedure:

Here we have been given the value of polynomial involving x. The question is about finding the value of this polynomial at x = -1. So, just substitute the value of x as -1.

Solution:

p (x) = x² - 5x + 4

When the value of x is taken as -1,

p (-1) = (-1)² - 5(-1) + 4

→ p (-1) = 1 + 5 + 4

→ p (-1) = 6 + 4

→ p (-1) = 10

∴ The value of x = -1 is 10

♧♧Given:-

• Polynomial P (x)=x^2-5x+4

♧♧To prove :-

• The value of P (x).

♧♧Explanation :-

• P (x)=x^2-5x+4

1. Here we should use the value of x as -1

♧♧Now applying the values ,

• P (-1)=(-1)^2-5 (-1)+4
• P (-1)= 1+5+4
• P (x)= 10.

Therefore,

• The value of P(x) is 10.
